Title: Process for Lacquer-coating Iron and Steel
IPC: B05D1/00
Filed: 1979-06-21
Abstract: The process according to the invention relates to the coating of iron and steel articles with lacquers in a magnetic field. Lacquers are employed which contain at least one ferromagnetic pigment. An increased magnetic flux in the region of edges, corners, points or the like has the effect of producing flawless (i.e. pore- free) coverage with lacquer in these regions. Increased deposition, compared with that or other surface parts, can also be achieved. The process is particularly important for the lacquer-coating of automobile bodies, machines and steel furniture. <IMAGE>

Title: Manufacture of rack member for rack and pinion assembly
IPC: B21K1/76
Filed: 1979-08-30
Abstract: A longitudinally extending rack member for a rack and pinion assembly is formed, e.g. by rolling, from a metal bar the grain 11 of which extends longitudinally of the bar and continuously over the length of the bar within which the rack teeth 7a are to be formed. The rack teeth 7a are formed by coin pressing between opposed dies so that the metal grain 11a follows the form of each tooth to be continuous over the array of rack teeth and each tooth 7a is devoid of end grain. Following coin pressing the teeth 7a are not subjected to machining so that the continuous grain is maintained to provide reinforcement against fracture of the teeth. The rack teeth 7a can be coin pressed in a machined recess in the bar which recess has opposed faces 4 and 5 within which faces end grain 12 is exhibited. <IMAGE>

Title: Method of and apparatus for drying wood
IPC: B30B9/20
Filed: 1981-01-09
Abstract: Wood in the form of relatively small pieces, such as the wood chips which are produced during a process of making chipboard, has its water content decreased by compacting a mass of the wood chips so that the faces of the separate wood chips are pressed against one another to squeeze water from their interiors. The water squeezed from the interiors of the wood clips is removed from the vicinity of the mass 7, while this is still under compaction, by drainage through apertures 6 in a perforated plate 5. Preferably the drainage is assisted by application of a low pressure. Advantageously the wood chips in the mass 7 are subjected to a pressure of 600 psi (42 kg/sq cm) for a period of about one minute. <IMAGE>

Patent GB-2116102-A (GB)
Title: Riveting tool
Inventor: GILBERT TERENCE
IPC: B21J15/28
Filed: 1982-03-08
Abstract: A pneumatically powered riveting tool for setting breakstem rivets has a riveting head (12) having means (26, 36, 38) for pulling a rivet stem so as to set the rivet and break off a tail part (46) of the stem, and an air injector (52, 50) which, when supplied with compressed air via a hose (76) and passages (78, 80, 82, 84, 64) induces a secondary flow of air whereby the broken off stem tails (46) are entrained so as to expel the stem tails from the riveting head (12) into a container (14) which is removably attached to the riveting head. A safety valve (94, 96) operates to disable the air injector (52, 50) and thus prevent ejection of stem tails when the container (14) is not in position to receive them. The safety valve operates to reduce the flow of air to the air injector (52, 50) either by cutting off the supply of air to the injector (52, 50) or by allowing the air supply to bleed away to atmosphere via the passage (84) before reaching the injector. <IMAGE>

Patent GB-821538-A (GB)
IPC: G03B39/00
Abstract: 821,538. Kinematograph cameras. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 19, 1957 [July 20, 1956], No. 22612/56. Class 97(1) A camera comprises a single image forming optical system and a number of reflecting surfaces grouped in non-parallel planes round its axis providing separate light paths for forming spaced images on sensitive material and means for selecting the light paths successively. In the form shown in Fig. 3 a pyramidal reflector F is mounted on the axis of an objective G. Light beams are directed past the object space O, through the objective, in different directions successively so as to impinge on different faces of the reflector. The separate reflected beams may form images on separate films or, by using reflectors as shown, different areas of the same film. The light beams originate in sources which may be formed by different points on a cathode ray tube or, as shown, by a ring of spark gaps S1...S5... which may be formed from a common central electrode and a ring of other electrodes and which are fired in sequence. Further images may be obtained by providing an outer ring of spark gaps which provide image forming beams incident on, and reflected from, the pyramidal reflector in directions different from those from the inner ring of spark gaps. These beams are intercepted by a further ring of reflectors and directed on to separate areas of the film. They may, alternatively, be directed on to the same areas of superposed films separated by a colour filter, appropriate filters being inserted in the separate groups of beams from the spark gaps. For photographing by reflected light the light paths may be rendered effective successively by a shutter in the form of an apertured disc rotating about the optical axis between the objective G (Fig. 6) and the reflector F. Thus a disc D having three equally spaced slots is clampedbetween members B, C having diametrically spaced holes, one of which registers with one slit. This forms a balanced assembly which is a force fit in the inner race of a ball bearing K rotated by blowing air through inclined holes in a plate A on to the balls of the bearing. The frequency of exposures may be increased by using a plurality of apertures in the disc D. The number must not be integrally divisible into the number of facets on the reflector F. Exposures may be made in superposition on films separated by colour filters through different shutter apertures if the latter are also provided with colour filters. The rotating shutter may be replaced by sequentially operator Kerr cells or a multiple cell with a common central electrode and a surounding ring of eiectrodes. Repeated exposures are prevented by controlling the total duration of illumination by, for example, a discharge lamp. Specification 818,404 [Group XV] is referred to.

Title: Vibrator unit
Inventor: HILL ARNE
IPC: B06B1/10
Filed: 1982-07-28
Abstract: In a vibrator unit for driving a penetrating element (16), such as a pile tube, two weights (10A, 10B) of equal sizes are put in synchronous motion in opposite directions each along one of two uniform and mutually parallel or bits located on opposite sides of and at equal distances from an axis (2) coinciding with the longitudinal axis of the element (16) in such manner that the weights (10A, 10B) always simultaneously cross a plane of symmetry of the two orbits coinciding with said axis (2) and between these crossings are on opposite sides of said plane of symmetry. The speed of weights (10A, 10B) cyclically varies during each revolution and reaches a maximum at one crossing of the weights through said plane of symmetry, whereby the penetrating element (16) will be subjected to unidirectional axial thrusts and at the same time to momentarily increased torques causing the element to rotate stepwise in a predetermined direction. Each weight (10) is pivoted to a fixed crankshaft (9) and is longitudinally slidable in a bearing (11) mounted by trunnions (12) in a flywheel (3). <IMAGE>
